Summary:

Introduction -- Plant cell walls constitute bulk of plant biomass -- Plant cell walls: cell type-specific -- Plant cell walls have many functions in the plant -- Plant cell walls have many uses -- Two general types of walls: primary vs. secondary -- Characteristics of primary & secondary walls -- Plant cell walls consist of interacting polymers -- Polymer content of primary & secondary walls -- Models of the plant cell wall -- Cellulose-matrix polysaccharide network -- Models represent cellulose, hemicellulose, pectin -- But what about the cell wall proteins? -- Cell wall proteome -- Arabinogalactan protein distribution in the cell wall -- Proposed extensin 3 networks in cell walls -- Proteoglycans in the plant cell wall (1) -- Proteoglycans in the plant cell wall (2) -- Model of cell wall containing APAP1 -- Structure and synthesis of wall polymers -- Overview of plant cell wall biosynthesis -- Lignin -- Lignin in xylem of Medicago truncatula -- Chemical structure of 3 types of monolignols -- Major ether and C-C linkages in lignin -- Lignin deposition is spatial and time-specific -- General pathway for lignin precursor production -- Symbolic nomenclature of monosaccharide -- The nucleotide-sugar interconversion pathway -- Cellulose (1) -- The cellulose-hemicellulose network -- Cellulose (2) -- The structural units and interactions in cellulose -- Cellulose synthase catalytic subunits -- CESAs reside in rosette structures -- CESA protein and rosette structural models -- Bacterial cellulose synthase complex -- Mechanism of cellulose synthesis -- Association of cellulose with other components -- Hemicellulose -- Hemicelluloses -- Hemicelluloses - xyloglucan -- H-bonding of xyloglucan to cellulose microfibrils -- Structural diversity in xyloglucan sidechains -- Hemicelluloses - mixed linkage glucan & mannan -- Hemicelluloses - xylan -- Cellulose synthase-like (Csl) genes -- Xyloglucan biosynthesis -- Mixed-linkage glucan biosynthesis -- Mannan and glucomannan biosynthesis -- Xylan biosynthesis -- Pectin (1) -- Pectins in middle lamella and throughout cell wall -- Pectin (2) -- Pectins: HG, XGA and AGA -- Pectin: Rhamnogalacturonan II (RG-II) -- Pectin: Rhamnogalacturonan I (RG-I) -- Interconnection between different pectic domains -- Homogalacturonan biosynthesis -- Xylogalacturonan and RG-II biosynthesis -- Rhamnogalacturonan I (RG-I) biosynthesis -- More research is needed on cell wall architecture -- Wall matrix polysaccharides are connected -- Why cell wall research is important -- Additional References -- Acknowledgements.
